Orange Free State postage stamp with strange overprint, orange tree, 1900

 Orange Free State postage stamp:

• Orange tree
• Issued 1900
• Used, hinged
• Color: Violet
• Denomination: I'm not sure

I'm not quite sure what to make of this stamp. Both the periods and the "I" are missing and it seems that the ink of the overprint was smudged. Also, it seems to be a 2 penny surcharge on a 1 penny stamp, however, this variety is not listed in the Scott catalogue. I don't know whether the cancellation is blocking the actual number, but as far as I can tell it must be Scott catalogue number 45, but I'm not sure which number 45. I have added photos of the catalogue below.

Stamp sold as per photos. Please do not hesitate to ask me a question as I cannot be held responsible for any errors that are visible on the image and are not noticed before purchase.

Additional items: free postage refers to items bought on the same day. I will package the item as securely as I can in order to limit potential damage during shipping, however, once an item has been shipped, the risk of loss and/or damage passes to the buyer, I accept no responsibility for loss or damage thereafter.
